Without knowing anything about Amarok, it looks like
your software is adding both ID3v1 and ID3v2 tags. Given the restrictions in ID3v1 (no selection of character sets, limited field sizes, very restricted set of tags) I know quite a few people avoid using them. For those people this is a useful script. If you have decided to live with the restrictions Amarok imposes then the script won't be useful for you, so just ignore it.

Before writing the script I did look at the Android BBs, where there are a number of complaints about exactly this topic and no easy to apply fixes. So the fact that your combination of tagger and phone don't suffer from this particular issue means that this particular script is no use to you, it does not mean the script is no use at all.
